It looks like it does fork since if I use jconsole, I will get a second JVM that has identical properties as the first. Part of the issue with this is I notice that both JVMs will have the amount of memory I specify for MAVEN_OPTS. In the above case, 1GB. If I run release:perform, the forked JVM is maxed at 1 GB of memory when the error occurs.
I did try to run the JVM with 1284 MB for the maven instance (which is the highest I can run it where the JVM will start), but in that case, my build dies sooner because it can't allocate enough memory for the forked instance. The initial instance of Maven2 only uses 40K of memory, so it's unnecessary for it to have as much memory as the spawned process. The server I'm building on, has 4GB of physical memory, but apparently enough isn't available to have the initial Maven2 instance and the spawned one both running at 1284MB of memory. Other than checking out the tag, is the only other thing that the release:perform does is a "deploy"? Ryan On Mon, Jun 8, 2009 at 10:35 AM, Baptiste MATHUS <[email protected]> wrote: > Interesting.
